Hello guys... Recently i bought a new computer setup. I bought the following and put it all together to upgrade my previous PC. CPU: AMD X4 640 3.0GHZ (DDR3) Mother Board: MSI 785GM-P45 (DDR3) RAM: Corsair Dominator 4GB (DDR3) GPU: EVGA Nvidia GT220 1GB HDD: Samsung F3 1TB 7200 RPM PSU: (I forgot the brand) 610watt So i put all those parts together along with a case to upgrade from my previous set up. Everything went well... My friend installed the OS (Windows 7 Ultimate 64bit) and everything ran smooth. Then when i brung it home from my friends house i hit the power button... my computer started up and BAM it was stuck on a black screen for super long and then BSOD... I spent a whole week with this comp trying to fix it and i cant get anything! Sometimes i would start up my computer and it would run smooth! like it automaticly fixed itself. Sometimes it would act up on me and go BSOD mode. If i cant find a solution to this problem or if the problem still persists then i will have no choice but to sell my comp. I really need you guys help. Please i would appreciate it. I will attach some dmp. files if that would help.
